What I Did: Every night, I wrote down the time I ate dinner, when I turned off electronics, and what time I turned out the light. The next morning I added my wake up time and a brief note about how I slept. Even after only a week or two sleep journaling, I saw some interesting patterns (or lack of patterns) and knew what I needed to work on to get better sleep.
After being awake for nineteen hours, people who were sleep-deprived were as cognitively impaired as those who were legally drunk… After sixteen hours of being awake, the brain begins to fail. Humans need more than seven hours of sleep each night to maintain cognitive performance. After ten days of just seven hours of sleep, the brain is as dysfunctional as it would be after going without sleep for twenty-four hours.
“This is number one—most of us have this reflex where our cellphone has to be within arm's length, even when we go to bed," says Raj Dasgupta, MD, sleep expert and assistant professor of clinical medicine at Keck School of Medicine of University of Southern California. "We need to break that habit.” Studies have shown that the blue light generated by electronic devices can delay the onset of sleep. (Here's how spending just one extra minute on your phone before bed can rob you of 60 minutes of sleep.) Turn your phone on silent and keep it on a dresser or far end of the bedside table so you’re not tempted to text, check one last email, or get lost in social media.
Melatonin supplements are widely recommended for various sleep conditions, but the best evidence is for help with sleep problems caused by shift work or jet lag. Melatonin is a naturally-occurring hormone that regulates the sleep-wake cycle in the brain. It is produced from serotonin when exposure to light decreases at night. It is used in conditions where sleep is disordered due to low levels of melatonin at night such as aging, affective disorders (e.g. depression), delayed sleep-phase disorder, or jet lag.
Mantram is the practice of repeating over and over in the mind certain syllables, words or phrases that help unify consciousness and counteract negative mental states. It is especially helpful for people with restless minds, whose turbulent thoughts keep them from relaxing, concentrating and falling asleep. The repetition of a verbal formula is a way of focusing the thinking mind and counteracting the damage done to both mind and body by thoughts that produce anxiety, agitation and unhappiness.
How is it possible to be sleep deprived without knowing it? Most of the signs of sleep deprivation are much more subtle than falling face first into your dinner plate. Furthermore, if you’ve made a habit of skimping on sleep, you may not even remember what it feels like to be truly wide-awake, fully alert, and firing on all cylinders. Maybe it feels normal to get sleepy when you’re in a boring meeting, struggling through the afternoon slump, or dozing off after dinner, but the truth is that it’s only “normal” if you’re sleep deprived.
You know what happens when you don’t sleep well: You feel sluggish in the daytime, and your concentration suffers. Poor or insufficient sleep has been linked to other problems, too, such as declined immune function and an increased risk of diabetes and high blood pressure. In your struggle to find out how to sleep better at night naturally, you’re willing to try just about anything.
REM sleep are particularly important. You can ensure you get more deep sleep by avoiding alcohol, nicotine, and being woken during the night by noise or light. While improving your overall sleep will increase REM sleep, you can also try sleeping an extra 30 minutes to an hour in the morning, when REM sleep stages are longer. See The Biology of Sleep to learn more.
When it comes to feeling tired of feeling so tired, I'm certainly not alone. Insomnia is incredibly common in the U.S., with 30 to 40 percent of American adults experiencing some symptoms of insomnia each year. [Etiology of adult insomnia]. Dollander M. L'Encephale, 2003, Mar.;28(6 Pt 1):0013-7006. So for anyone out there who has developed an expertise in fruitlessly counting sheep, we've rounded up a few strategies for finally catching those long-lost Z's when you can't sleep. And if you’re reading this at 3 a.m. because your mind won’t stop racing, don’t worry; we have tips for what you can do right now to improve the chances of getting (at least some) sleep.
How long does a cup of coffee keep you awake? Caffeine stimulates the nervous system. People often consume it to stay alert, but how long do effects last, and how does it impact sleep? This depends on many factors, including the amount of caffeine ingested at once and an individual's metabolism. Learn to estimate how long the effects of caffeine last here. Read now
SOUND: We focus on sound a lot. Quiet environments are going to improve your sleep quality. Your brain has these micro arousals throughout the night without you being consciously aware of it—even an air-conditioning unit turning on wakes up your brain. So blocking out noises is a low-hanging fruit to improve your sleep quality. Bose just released an earbud that you can sleep with, for example.
The research looked at simple carbs, which are quickly and easily digested. These include things like white rice, white bread and pasta, and potatoes (as well as sugary foods). Interestingly enough though, a Japanese study only found sleep benefits from rice and not from bread or noodles. If you are trying to minimize carbs, it may be most beneficial for your sleep to at least eat a serving for dinner.
During the late '60s and early '70s, sleep studies suggested that the neurotransmitter serotonin may play a role in sleep induction. Later on, research in animals showed that destruction of parts of the brain that housed nerve cells containing serotonin could produce total insomnia. Partial damage to these areas of the brain caused variable decreases in sleep. The percentage of destruction of these particular nerve cells correlated with the amount of slow-wave sleep.
Glycine (also known as 2-Aminoacetic Acid) is an amino acid and a neurotransmitter. The body produces glycine on its own, synthesized from other natural biochemicals. We also consume glycine through food. This amino acid is found in high-protein foods including meat, fish, eggs, dairy and legumes. A daily diet typically includes about 2 grams of glycine.
Postpone worrying and brainstorming. If you wake during the night feeling anxious about something, make a brief note of it on paper and postpone worrying about it until the next day when it will be easier to resolve. Similarly, if a great idea is keeping you awake, make a note of it on paper and fall back to sleep knowing you’ll be much more productive after a good night’s rest.
Everyone needs sleep, but its biological purpose remains a mystery. Sleep affects almost every type of tissue and system in the body – from the brain, heart, and lungs to metabolism, immune function, mood, and disease resistance. Research shows that a chronic lack of sleep, or getting poor quality sleep, increases the risk of disorders including high blood pressure, cardiovascular disease, diabetes, depression, and obesity.
